Answer
Bob,

That was a common problem on your car. There were updated gaskets and bolts for the exhaust buzz. As long as they put them on, the buzz should be gone.
I doubt that they did anything to create the buzz while doing the timing belt. They do not get anywhere near the exhaust when doing a timing belt. You were probally just more in tune with all the noises when you picked the car up and just never heard it before. I would look under the car where the A-pipe meets the mid pipe. You should be able to tell by the shiny new bolts if they really did the update.
Good luck and thanks for the question.
